WATER-MOTOR.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed December 24, 1908. Serial No. 469,166.

To all whom it may concern:

Be it known that I, JULIUS HUBMANN, a citizen of the United States ofAmerica, and a resident of the cityof Tacoma, county of Pierce, andState of WVashington, have invented certain new and useful Improvementsin Water-deters, of which the following is a specification.

My inventionrelates to apparatus of the above type and aims primarily toprovide means for controlling the ingress and egress of water whereby aconstantly changing level of the water in the float chamber can beobtained to effect an alternate rise and fall of the float.

Other objects will be set forth as my description progresses and thosefeatures of construction, arrangements andcombinations of parts in whichmy invention resides, succinctly defined'in my annexed claims.

Referring now to the accompanying drawings, wherein my invention, insuch form as now preferred by me, is. illustrated: Figure 1 is alongitudinal sectional view of my invention. Fig. 2 is a top plan viewthereof, and Figs. 3 and 1 are detail views, on enlarged scale.

Reference numeral 1 indicates the float chamber having ingress andegress openings 2 and 3 respectively, arranged one above the other andcontrolled by gates 4. This chamber can be of any desired constructionand formation and gates 4, in the broad spirit of my invention, can beof any desired type. As now considered, however, I form gates 4: inhorizontal sections, which latter are pivotally supported in the sidewalls of the openings 2 and 3 of the float chamber, and are so arrangedas to when closed, overlap one another to prevent leakage of the watertherebetween.

Slidably supported operating members 5, in the form of bars, areconnected by links 6 to the respective sections of gates 4. for swingingthe same, see Fig. 1.

In the resent embodiment of my invention, mem ers 5 are slidablysupported on pins 7, secured to relatively fixed parts of the apparatus,said pins engaging in slots 8 of said members.

Slots 8 have off-set end portions and pins 7 in traveling through thesame efiect a slight lateral movement of the members 5 to insure of amore perfect closing operation of the gate sections.

Reference numeral 9 indicates a walking beam, the end portions of whichhave slotted connection with members 5. Walking beam 9 extends over thefloat chamber 1 and is pivoted at 10, on a cross member 11 of a suitableframe 12.

Reference numeral 13 indicates a notched segment provided on walkingbeam 9, in the notches of which a detent 14 of a lock bar 15, pivoted at16 on frame 12, is adapted to engage to hold the walking beam againstmovement.

In the float chamber 1, a float 17 is supported for vertical sliding onsuitable guides 18, andthis float can be connected with any suitablemechanism so as to, during its vertical sliding movement transmit powerthereto. In this connection, for the purposes of illustration, I haveshown float 17, provided with a rack bar 19 with which meshes a pinion20.

Pinion 20 is carried on one end of a shaft 20, journaled on frame 12,which shaft is provided on its other end with a crank 21 connected withthe piston of a pump 22.

Reference numeral 23 indicates weights pivoted to frame 12, as shown,beneath the opposite end portions of walking beam 9 and havingreleasableconnection therewith through the medium of links 2 1, see Fig. 1, whichlinks while loosely receiving the end portions of the walking beam aremade fast to the weights so as to move therewith.

On lock bar 15 I provide a pivoted link 25 and a relatively fixeddepending arm 26, the latter of which lies in the path of a strikemember 27, carried on the float.

Link 25 is connected to a lever 28, fulcrumed at 28 and connected to arod 29 which extends through float 17 and is provided with a collar 30which when engaged by strike lugs 31 of the float, upon lowering of thefloat, swings lock bar 15 to free walking beam 9. Swinging of lock bar15 to other can operate. To effect this result, I provide lever 28 withan upwardly extending arm 32 for engagement with one weight 23, andfloat 17 with a suitable strike arm 83 for engagement with the other ofsaid weights.

Referring to Fig. 1 the operation, briefly stated, is as follows: Waterdischarges through egress opening 3, allowing float 17 to lower untilstrike lugs 31 engaging collar 30 on red 29, swings lever 28, to causelink 25 to elevate lock bar 15, and arm 32 to elerate the adjacentweight 23, when the other weight will swing walking beam 9 to operategates 4. to open ingress opening 2 and close egress opening 3. lVhenfloat 17 again starts to rise lock arm 15 is permitted to fall to engageits detent 14 in the other notch of segment 13.

\Vater can be directed for discharge into the float chamber, as througha race-way 34, from any desired source of supply.

During upward movement of the float, arm 33 elevates the other weightand lock bar 15 is elevated by arm 26 being struck by member 27, aspreviously described to effect movement of the gate sections to theposition shown in Fig. 1.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, of the United States of America, IS I 1. In awater motor, a float chamber provided with ingress and egress openings,gates for said openings of the float chamber, said gates being formed ofsections supported for movement, means connecting the sections of eachgate for simultaneous movement, means to lock the gate sections againstmovement, a float in said chamber, and means controlled by said floatfor operating said first means to alternately open the openings of saidchamber to passage of the water.

2. In a water motor, a float chamber provided with ingress and egressopenings, gates therefor, a float in said chamber, means controlled bysaid float to alternately open said gates, means for locking said gatesagainst movement, and means operated by and during movement of saidfloat to operate said lock means to a releasing position.

3. In a water motor, a float chamber pro vided with ingress and egressopenings, gates therefor, a float in said chamber, means controlled bysaid float to simultaneously open one gate and close the other, meansfor locking said gates against movement of said float, and means tooperate said lock means to a releasing position.

4. In a water motor, a float chamber provided with ingress and egressopenings, gates therefor, a float in said chamber, means controlled bysaid float for alternately opening said gates including a pivoted membereach end of which is connected with a respective gate, means to locksaid swingingly supported member against movement, and means operated byand during movement of said float to release said last means.

5. In a water motor, a float chamber provided with ingress and egressopenings, gates therefor, a float in said chamber, means forsimultaneously opening one gate and closing the other, lock meanscontrolled by said float for holding said first means against movement,and means for operating said first means after it has been released.

6. In a water motor, a float chamber provided with ingress and egressports, gates therefor, a float in said chamber, means for simultaneouslyopening one gate and closing the other, lock means controlled by saidfloat for holding said first means against movement, and a weight foroperating said first means after it has been released. 7. In a watermotor, a float chamber provided with ingress and egress openings, gatestherefor, a float in said chamber, a walking beam, means connecting saidgates with the end portions of said walking beam for operation thereby,weights releasably connected with said walking beam, one weight normallycounter-balancing the other, and means controlled by said float foralternately releasing said weights from said walking beam.

8. In a water motor, a float chamber provided with ingress and egressopenings, gates therefor, a float in said chamber, a walking beam, meansconnecting said gates with the end portions of said walking beam foroperation thereby, weights releasably connected with said walking beamon opposite sides of the fulcrum point thereof, and means foralternately operating said weights to a releasing position controlled bysaid float to be operated as the latter rises and falls.
